ing closed at top by a removable cap 9 Above the base 9 the reservoir-casing is divided by a horizontal partition 9, forming a valvechamber 9 for the alcohol-valve 72/ below and the alcohol-chamber above. This partition g is formed with a port 5/, controlled by a screw-plug or valve I. In Fig. 5 the arrangement is essentially the same, the only difference being that the stem of the valve it rests upon the upper end of a spring puppet-valve a, which latter opens downward, thereby lowering the valve h to its seat and cutting off the alcohol in the valve-chamber g the alcohol contained in the space between the two valves being admitted to the air-induction passage a, whereas in the arrangement shown in Figs. 1 and 2 the alcohol from the valve-chamber g and from the reservoir above is free to flow downward as long as the air-valve a is open.

It is to be understood, as heretofore intimated, that the electric sparking and the introduction of alcohol into the induced air-supply is desirable only in starting the engine oruntil such time asthe ignition-bulb D acquires the degree/of heatrequisite to flash the charges of oil independently of the electric spark. During the use, of the electricspark and vapor of alcohol the usual feed of oil occurs; but since it takeslonger to explode the combined charge by means of the electric spark than it does by means of the ignition-bulb D when fully heated, it is desirableto introduce the oil at about one-third of the compressionstroke of the piston B when running under normal conditions, owing to the relatively greater heating-surface of the bulb D. For this reason we arrange two feed-cams J and J upon the cam-shaft K and make the roller Z on the rocker -arm L, which operates the oil-pump P, adjustable with relation thereto, as will be seen by reference to Figs. 1 and 3 of the drawings, in which the positions of the rollerZ is controlled by the hand-lever M, acting through the slide m and arm m, the lower end of which latter is bifurcated and engages with shoulders Z Z on the rolleraxle Z. A detent '22 holds the parts in either one extreme of thrust or the other, according to the cam to be brought into action indirectly upon the oil-pump. Incidentally the handlever M is used as a switch to throw into or out of electric circuit the sparking device F. Thus when the lever M is thrown over to bring the roller Z into coincidence with the earliest acting cam J the lower end of said lever M is thrust against the electric contact 0, and the circuit in which the sparking device F is interposed is completed.

In starting the engine it is only necessary to throw over the lever M to the right until 'ally introducing alcohol into the induced airits lower arm abuts against the contact 0, the port g being also opened by screwing up the plug I, when the first revolution of the crankshaft by hand starts the operation, the alcohol mingling with the induced air-supply and being exploded by the electric spark and this being continued for the first few revolutions until the bulb Dis sufliciently heated. When the port g is closed by the screw-plug I the lever M' is reversed and the engine assumes its normal running condition.

The quantity of oil supplied by the pump P may be varied at any time, no matter which of the cams J J is in action, by means of the hand-lever and connections R 7', controlling the rocker K in the usual manner.

The degree to which the valve h is raised from its valve-seat g is regulated by turning the cylinder g upon the thread it, formed upon the upper part of the union H, thereby regulating the flow of alcohol to the air-induction passage (0. I

What we claim as our invention, and desire to-secure by Letters Patent, is

1. In a kerosene-engine, means for introducing oil into the combustion-chamber thereof, means independent thereof for automatically introducing alcohol into the induced airsupply, and means for automatically changing the time of oil feed.

2. In a kerosene-engine, means for introducing oil into the combustion-chamber thereof, means independent thereof for automaticsupply, and means for automatically changing the timeof oil feed and throwing the sparking device into electric circuit.

3. In a kerosene-engine, means for introducing oil into the combustion-chamber,means I 00 for causing an induced air-supply, means in addition to the oil-introducing means, and independent thereof for introducing alcohol into the induced air-supply, and means for simultaneously changing the time of oil feed and 5 throwing a sparking device into electric circuit.

4. In a kerosene-engine, means for introducing oil into the combustion-chamber,means for introducing alcoh'ol into the induced air- I I0 supply, means for exploding the combined charge by an electric spark, and means for simultaneously changing the time of oil feed and throwing the sparking device into electric circuit, substantially as and for the pur- 1 5 pose described.
